BALlNG-PRESS- Specification of Letters Patent.

Patented April 24, 1906.

Application filed January 5, 1901. Serial No. 42,224.

To a whom it may concern.-

Be it known that I, MosEs C. NIXON, of the city of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Baling- Presses, of which the following is a specification.

My invention relates to that class of balingpresses commonly known as continuous or perpetual presses; and the objects of my invention are to improve the gear by means of which the plunger is operated, to improve the means of operating the feeder, to provide improved means for conveying the material beneath the said feeder, and to otherwise improve the machine; and it consists, essentially, in the construction hereinafter more specifically described and then definitely claimed.

Figure 1 is a side elevation of my improved press, parts being broken away to better show the interior construction. Fig. 2 is a plan view of the same, also partly broken away. Figs. 3 and 4 are details of the gearing operating the mechanism for conveying the material to the feeder.

In the drawings like letters of reference indicate corresponding parts in the different figures.

The body or case of the press is lettered A and is mounted upon a running-gear, such as is usual in this type of machine. Mounted upon the shaft D a belt-pulley D is shown, which is adapted to receive and transmit power to the gear-wheel E by means of gearpinion F. The gear-Wheel E is loose upon the shaft G and its hub is provided with a lug a. Secured to the shaft G is a collar H, provided with a similar lug b. By the rotation of the gear-wheel these lugs may be caused to engage and the shaft driven; but the form of connection permits the shaft at any time to run ahead of the gear-wheel. Upon the shaft G are secured the gear-wheels I, meshing with the gear-wheels J journaled upon stud-shafts projecting inward from the frame of the machine. The gear-wheels I and J are similar and of peculiar construction, as shown. The opposite ends of each gear are arcs of circles struck substantially from a common center, but with different radii. In each arc the number of teeth is the same, and the teeth between the ends of these arcs are struck on a suitable curve to enable the gear-wheel to mesh properly with the teeth of the gear-wheel with which it is expected to engage. The proportions shown in the drawings are substantially correct; but in any case a skilled mechanic would be able, when given the number, size, and pitch circles of the end teeth of the gear, to [ill in the sides in a satisfactory manner. It is not the intention to limit the invention in these gears to the exact construction herein described, for the ends could be varied somewhat from an exact arc struck from a common center and still obtain practically the same results. The purpose of so constructing these gears will be more particularly described when the general construction of the machine has been more fully set out. The power-crank is formed by connecting the gear-wheels J by the wrist-pin K.

The pitman L is suitably connected with the plunger B and the wrist-pin K and is constructed of parallel parts to permit of the cam M of the operating-lever N passing between its two parts. This cam M is shaped substantially as shown, its middle part being curved forward toward the plunger to meet the upward stroke of the wristpin K or other suitable connection with the power. The shape of the cam and movement of the wrist-pin transmitting the power causes the motion of the feeder to be slow at the upper and rapid at the lower portion of its stroke, thus enabling it to enter the press-chamber after the plunger has been withdrawn and escape out of the way as it again advances. The feeder-arm is pivoted on the frame of the machine at c, as shown in Fig. I. As the pivot c is preferably at or below the level of the shaft G, the feeder-arm is bent, as shown, to permit of it descending to a horizontal position without interfering with the shaft. P is a feeder of ordinary construction and preferably pivotally connected to the end of the feeder-arm O. Q is a jointed arm pivotally secured at (I to the frame of the machine and fast at e to the feeder P. To the end of the operating-arm N is pivoted a rod R, which passes through a block 9, pivotally connected to the feeder-arm O. The end of this rod R extends above the feeder-arm and has a nut f or other spring-retaining device secured thereto.

Between the end of the operating-arm and the feeder-arm is placed a coil-spring, and a similar coil spring is placed between the feedenarm and the nut f or other spring-retaining device. The purpose of this connection is that when the feeder-is brought rigid; but by down by the action of the crank wrist-pin K on the cam-arm M its operation will not be the yielding connection shown no damage will be done by the feeder striking solid lumps of material or being otherwise prevented from reaching to the full ordinary limit of its stroke. The yielding connection below the feeder-arm serves as a cushion to ease the jar when the feeder having reached the lowest part of its stroke is rapidly thrown upward by its operating mechanism.

Other arran ements of the yielding connection may e made without departing from the s irit of my invention.

The yie ding spring connection below the feeder-arm acts as a cushion and also forms a pushing connection, as the operating-arm by its means pushes up the feeder-arm and the similar connection above the feeder --arm forms a pulling connection, as by its means the operatinglever pulls down the feederarm.

Another advantage of the feeder being operated by the arm N is that the swing or stroke of the feeder can be regulated by making the said operating-arm longer or shorter, and other well-known flexible connections between the operating-arm and the feeder-arm might be employed.

The rear part of the receiving and feed hopper S is provided with a slotted bottom or feed-platform 0. Through the slots work the teeth h, carried by endless chains running on sprocket-wheels i on shafts with suitable journal-bearings on the frame of the machine. The forward end of this slotted bottom or platform is curved downward, as shown, and

serves as a stripper for the teeth. Above the front end of this slotted bottom is located a hollow partition T, suitably slotted at its lower rear'side and bottom to permit of the passage of the projecting teeth 0f the revolving shaft 7c. Between this partition T and the bottom C is a suitable opening through which the material to be pressed is conveyed beneath the end of the feeder P. As the teeth on the revolving shaft 76 travel at a higher rate of speed than thosecarried by the endless chain, they serve to tear apart the material that is being fed into the machine,

thus reventing the machine from choking and a so helping to facilitate the feeding.

Of course other well-known forms of conveyersmight be employed to carry the mate rial to the revolving teeth 7' and under the "feeder 'iP. The mode of'operatin this mechariismis as follows: To the end 0 the shaft 7c is secured a bevelgear-wheel Z. (See Figs. 3 and 4.) With this bevel gear-wheel meshes the bevelgea'r-wheel m, secured to the vertical shaft 1. The lower end of this vertical shaft bears a bevel-pinion -0., which meshes "withthe bevel gear-wheel 10, secured to the end of the shaft 8. With the bevel gearwheel 10 meshes the bevel-pinion 1", secured to the shaft g 'of the forward sprocket-wheels t.- The shaft 8 is journaled upon suitable bearings, and its other end is provided with a bevel-pinion t, which meshes with the bevel gear-wheel u, loose on the shaft G. t is a spring operating the sliding half of a clutch of any suitable description, by means of which the bevel gear-wheel 1/, maybe put into driv ing connection with the shaft G. The clutch is operated automatically by means of a cam b affixed to the sliding and revolving half of the clutch coming into contact with a suitably-carried stationary cam b, which is so placed as to be engaged once every revolution by the cam 1). Thus once every revolution the bevel gear-wheel a is thrown out of driving connection with the shaft G and the mechanism conveying the material to the feeder. is stopped just at the moment the feeder P is descending into the hopper to force the feed down in front of the plunger and the conveying mechanism-does not resume operations until the feeder again rises out of the way on its upward movement, it being the intention to provide automatic means to cause the conveyer to cease delivery of material to the feed-op eningduring the time the feeder is in the feed-opening to prevent accumulation of material against said feeder. The lever A is pivotally connected with the clutch in the ordinary manner and also to a fixed bearing and is used for the purpose of holding the clutch out of contact and thus stopping the material from beingcar-ried into the feed-opening at the time it is desired to place division-blocks in the machine or for other purposes. There is nothing particularly novel in the discharge end B of the press, as this is shown and described in prior patents, and detailed description is here unnecessary.

Having nowdescribed the construction of the machine, it is possible to explain more fully the peculiar advantage of the particular construction of the gear-wheels I and J already described, which is that the forward stroke of the plunger is rapid, while there is but little resistance. Then as it advances it slows down and the power increases until it reaches a maximum, which is maintained to meet the uniform resistance during the remainder of the stroke, when it is very rapidly returned for the next forward stroke. Though the power of the gearing is as described the toggle action of the pitman L ITO ism for decreasing the speed and increasing the power increase the power up to a certain point and then immediately commence to decrease, so when it is desired to maintain a great maximum power during a part of the stroke the advantage of my improved gearwheels is obvious.
